can I just stop taking hydroxychlorquine and hydrocortisone all at once or must I gradually decrease it.I was told I have sjogrens syndrome and have been on these meds plus levothyroxine, tribenzor, simisvistan, vitamin d, potassium for several years. I have recently developed floaters in my right eye and despite having new glasses with bi-focals can not read without taking them off. I believe I have been mis-diagnosed and want to stop the hydroxychloroquine and hydrocortisone immediately. I have osteoarthritis, high blood pressure, and sleep apnea.
